A study led by Jeffrey Blumberg at Tufts University in Boston revealed a unique class of polyphenols in cranberries are what prevents E. coli from adhering to cells, a mechanism that reduces the risk of certain types of infection, especially those caused by E. coli like urinary tract infections.

Cranberries also contain nutrients that act as antibiotics, which combat the herpes virus, maintain gastrointestinal and oral health, prevent kidney stones and help manage cholesterol.

Scientists continue to identify new mechanisms that establish cranberries as anti-cancer agents, but it's most definitely the phytonutrients in cranberries that are especially effective in lowering our risk of unwanted inflammation, which is most helpful with vascular issues.

What’s interesting is that research has shown that a phytonutrient, anthocyanin, which is natural anti-histamine, is increased when cranberries are exposed to natural sunlight. Therefore the harvesting technique of flooding the bogs to make the berries float actually increases the berry’s unique antioxidant and anti-inflammatory properties because it exposes the berry to greater amounts of natural sunlight.

Researchers also point out that cranberry benefits are found only in the whole berry because when juiced in the lab, skins and flesh typically contain the bulk of the vital phytonutrients.

Fresh cranberries contain the highest levels of beneficial nutrients. Firmness is a primary indicator of quality, so be sure to select cranberries that are firm to the touch and deep red – the deeper the color, the higher the beneficial compounds.

Fresh cranberries can be stored in the refrigerator for up to 20 days and may be frozen for up to 12 months.

To freeze, spread fresh cranberries on a cookie sheet and place in the freezer. In a couple of hours, the fully frozen berries will be ready to transfer to a freezer bag. Don't forget to date the bag before returning it to the freezer. Once thawed, frozen berries will be soft and should be used immediately.
